I ordered your handheld and I can't wait to receive. MY questions is:
Does the hand held give the same performance and horsepower improvements that changing the ecm does? I know the trans tune helps a lot, but I am trying to find out if there as any difference in performance when you were changing the ecm's compared to the hand held.
